Internal Power Supply Reset Timing Diagram
Notes: 1. tOFF compensates for the power oscillation period caused by the momentary power
supply oscillations.
2. Specified at 4.5V for a 5-Volt operation and at 2.7 for a 3-Volt operation.
3. If 4.5V is not reached during the 5-Volt operation, the internal reset circuit will
not operate normally. Under this condition, PT6880 must be initialized using the
instructions.
